Application filed June 16, 1927, "Serial No. 199,236.

My invention relates more particularly to containers equipped with valves, especially for the lower, discharge, outlets thereof, of

the type which are moved toward and away from the seats with which they cooperate, by rotation in one direction or the other, as for example by providing threaded engagement between the valve mechanism and a relatively stationary part of the container structure.

l have devised my invention for use more particularly, though not exclusively, in tanl: cars in which valve mechanisms control the lower outlets thereof and wherein, under vibration to which the valve mechanisms are subjected in travel over thetracks and the lashing of the contents of the t for of the valves becoming backed off presented.

My primary objects are to providen'ieans whereby danger of accidental backin oil of the valves, and resulting in lean of the contents of the tanks, is prevented; provide a mple, positively ope'ratingand economical construction of means for accomplishing this purpose; to providemoans for this purpose which will become automatically operative upon the seating of the valve, thereby avoidmg the necessity of relying upon the operator setting the l'l'lGCllElnlSll'l into functioning position; to provide means functioning as above stated and so constructed that should the vertica-l diameter of the tank become increased, as for example by the turning of the tank on its side, as in the case of an acsident, the discharge valve will not become opened and without subjecting the parts of the valve me; hanism and other parts associated therewith from becoming undulv strained; and other objects as will be manifest from the fol lowing description.

Referring to the .accompanyingdrawing, in which I have illustrated my invention as applied to the lower, discharge, opening of a tank car, the view therein shown is a vertical sectionalelevation through the por tion of the tank car at which theoutlet open ing and thevalve mechanism therefor is lo- I cated, certain parts of'the car and a portion part of the tank cars-is represented at-l, the

manhole therein being indicated at 2z-and shown closed by a cover 3. The plate por tion 4 represents the bottom of the tank and contains the lower discharge opening 5 affording a valve seat 6 and through whichthe contentsof the tank may be discharged. f;

The outlet 5 is controlled by valve mechanism represented generally at 7 and shown as comprising a valve proper 8 adapted tocooperate witlrtlie valve seat 6 and carriedby the lower end of valve-actuating means com prisinga lower bar section 9 and an upper barseetion 10 connected together for rotation as a unit. The lower bar section 9 with the lower end of which the valve 8 is operatively connected, is externally threaded as represented at 11 at which it engages the thread of athreaded opening 12 in aplate 13 supported above the bottomplate 4 by studs 14 connected with the latter, the upper end of the section 9 being shown as forkedl5 to receive the lower end of they rod section 10 which is connected thereto by a pin 16.

v The rod section 10 is non-circular in cross section, it being shown as of-square' cross section, and extends upwardly-through, and is rotatable in, an opening in a bracket 17 secured to and extending inwardly from, the vertical wall of the (1011101.

Slidable up and down on the rod Section 10, above the bracket 17, is a hand wheel 18, the opening through the latter being of the same shape the cross-sectional shape oftho rod section 10 to cause the wheel 18 and rod to rotate as;a unitary structure, the rod sec-2 tion 10 at its upper end-being provided with. a stop pin 19 which normally operates to pre-,

vent the wheel 18 from being lifted off the rod section 10 but which is of such material and, size that it will yield andperimt the wheel to become disengaged from the rodi and 7 not,

overstrainthe valve and the other parts of type shown, when the car; is in transit, is'to.

rotatefi'n a directionto lift thevalve8 fromthe seat 6, this tendency being overcome, ac cording to the preferred illustrated embodiment ofmy. invention, by providing means. which operate automatically in the travelof the car over the track, to exertsagainstthe.

ber-2O depending from the hand-wheel 18" and being shown as in the form of asleevelike member with its lower edge shaped to afford a cam; andthe cam 'member 21 being shown as in the form of a plate resting upon theupper surfacexof the bracket 17 and sc cured thereto by the bolts 22 with an upwardly extending-boss-portion the upper surface of'which presentsthe lower cam, this plate withits boss portion containinga vertically disposed circular opening registering with the opening in the bracket 17 and through which the rod section upwardly extends and in which the latter is rotatable.

The operation of the mechanism is as follows:

Assuming the valve Sto have been lowered against the seatfi, as shown in the drawing, bythe operator rotating the hand wheel 18, the latter having been preferably preliminarily raised to'a position-in which the cam clears the canr21, the release of the grasp of the operator on the hand wheel 18 causes it to descend on the rod section 10 to engage 7 its cam 20 with the cam 21. The wheel 18 val having been applied to such an annular-position upon the rod section 10 that its cam surface 20 will occupy substantially the position shown in the drawings relative to the cam surface 21 when the valve is in seated position, the tendency of the cammember 20, under the combined'weight of this member and the wheel 18, is to slide down the cam 21 and thus exert on the rod sect-ion 10 force ten-ding to rotate it in clockwise direction and thustending to press the valve 8 toward the seat 6. Thus vibrations produced'in the valve mechanism and which would have a tendency to unscrewthe rod from the support 13 are caused to-produce a directly opposite efiect, namely, rotation of the rod in a directionto'seat the valve.

Furthermore, the provision of the cam mechanismas described operates to prevent lateral.

vibration of the rod in the opening in the bracket 17 thus-steadying the valve rod, preventing vibrationthereof and avoiding undue wear of these parts; a

The hand-wheel 18 being slidable along the rod section 10, variations in the vertical distance between the threadedsup'por't 13 and r the braeket ll, such" as occununder;variations in load-ingof the 'car aud t/he shifting movement of its contents or distortion of its;

walls, particularly. in case "of accident,*do not result in the subjecting of the valve mechanismgor the pants associated therewith, to un due strainaand have no-efi'ect on the proper functioning of the cam mechanism described,

which automatically adjusts itself to such variations. Should the Vertical distance referred to become excessive, the safety pin 19 will yield, permitting the hand wheel to disengage from the rod sectionlO to avoid undue strains on the parts referred to and ensure against accidental opening of the valve 8 and the discharge of the contents of the car.

While I have illustrated and described a particular construction embodying my invention and shown a particular embodlment thereof, I do not wish to be understood as intending to limit it thereto as it may be used in other situations and the form of itsem- .bodiment modified and altered without departing from the spirit of my invention.
